pycontrails.SAFBlend

class pycontrails.SAFBlend(pct_blend)

Bases: Fuel

Jet A-1 / Sustainable Aviation Fuel Blend.

SAF only changes the CO2 lifecycle emissions, not the CO2 emissions emitted at the aircraft exhaust. We assume that the EI OC stays the same as Jet A-1 fuel due to lack of data.

Parameters:

pct_blend (float) – Sustainable aviation fuel percentage blend ratio by volume, %. Expected to be in the interval [0, 100].
